Rails offers a variety of methods for generating unique DOM IDs
and classes for elements on a page.
One such method is the
which can generate a unique ID for a specific object or model.
However, by default, the
only generates an ID
and does not include any classes.
Rails has added a new feature
that allows the
to also accept a class.
This allows developers to generate both an ID
and a class for an element without the need to use different methods for generating IDs
Before this feature was added,
developers would have to use the
dom_id method to generate an ID,
and then use a separate method such as
dom_class to generate a class.
developers would have to use separate methods to generate both an ID
and a class for an element.
Let’s assume we have a User model
and we want to generate the
dom_class for it.
We would write the following code:
As we can see, this requires two separate lines of code, one for the ID and one for the class.
With the new feature, developers can now generate both an ID
and a class in a single line of code using the
As we can see, this is a much more concise and efficient way of generating both an ID and a class.
Additionally, if we want to add a custom class, we can pass it as a second parameter.
Now, they can use the
dom_id method to generate both an ID
and a class at the same time,
saving them a few keystrokes.
Overall, the ability for the
dom_id method to accept
a class in Rails is a welcome addition for developers.
With this PR, developers can write more efficient
and maintainable code.
